Weiler Tiger AO 2.0 type 27 depressed center cutting wheels are the next evolution in abrasives. These wheels now last up to 40% longer without sacrificing cut-rate, resulting in fewer change-overs and more cuts over the life of the wheel. Premium aluminum oxide grains offer a smooth, consistent cut-rate for an exceptional combination of performance and value when cutting steel or other metals. The Tiger 2.0 upgrade features a QR code on the wheel for quick access to important safety information and a patent pending Optimum Use Line to help get the most out of the wheel. Using the wheel to its full life reduces change-overs, which helps users be more productive while reducing waste and abrasive spend. The depressed center or raised hub provides added clearance when working at a constrained angle. The .045 wheel thickness is ideal for cutting tubes, bar stock, and large cross-sections with a right angle grinder. A 7/8" open arbor offers a cost-effective mounting option when using adapting nuts. These versatile 6 inch AO cutting wheels offer an even longer life solution for all your general purpose applications at an excellent total cost of use.
